Abstract

Of the myeloproliferative neoplasms (MPNs), myelofibrosis (MF) is associated with the greatest symptom burden and poorest prognosis and is characterized by constitutional symptoms, cytopenias, splenomegaly and bone marrow fibrosis. A hallmark of MF is dysregulation of the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway that has led to the development of JAK inhibitors targeting this pathway. Calreticulin gene mutations have recently been identified in JAK2 mutation-negative patients with MF. Identification of JAK inhibitor resistance and broad contributions to MF disease pathogenesis from epigenetic deregulators, pathways that work in concert with JAK/STAT (that is, mammalian target of rapamycin/AKT/phosphoinositide 3-kinase, RAS/RAF/MEK, PIM kinase), fibrosis-promoting factors and the MF megakaryocyte, suggest that numerous options may be partnered with a JAK inhibitor. Therefore, we will discuss logical and potential partners for combination therapies for the treatment of patients with MF.
